BOTTLE-CAPPING ivrncnrnn.

To all whom it may concern:

Be it known that we, JOHN J. GAYNoR and PETER CARL LIEBER, citizens of the United States, and residents of Indianapolis, county of Marion, and State of Indiana, have invented a certain new and. useful Botole-Capping Machine; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings,in which like letters refer to like parts.

The object of this invention is to improve the construction of compensating mecha-' nism in bottle capping machines in the type set forth in our applications for bottle capping machines, Serial No. 7 86,080, filed August 21, 1913, and Serial No. 797,554, filed October 27, 1913.

One feature of the invention consists in improvements in the compensating device for supportingthe bottles and the like, and particularly means for controlling and operating the dog which initially receives the downward movement of the bottle support when the strain becomes excessive.

In a former application there is shown in the lower part-of the bottle support a dog mounted so as to wedge between the fixed beveled plate and a movable beveled plate and to have frictional resistance during the entire movement thereof after the initial movement. In the present invention the dog is controlled by an upwardly pulling spring, the tension of which is adjustable and said spring holds the lower end of the dog on the beveled endof afixedplate below, which resists the downward movement of the ,dog and, therefore, the bottle support until the strain becomes sufliciently great to force the lower end of the dog off said fixed plate, and thereafter there is no appreciable resistance to the downward movement of the spring support so far as these parts are concerned, but such further resistance is performed by a spring independent of said dog and fixed plate. This last-mentioned spring is a spiral spring located between the movable bottle support and fixed means on which said bottle support is mounted, so that said spring resists the downward movement of the bottle sup-- port at all times and particularly after the initial-movement, and said spring also returns the bottle support and on the return said first-mentioned spring returns the dog to its normal position. There is also in the p s nt invention an improv d means t r limiting both the downward and upward movement of the bottle support.

The bottle support 15, see Fig. 2, upon which the bottle rests, has screwed on its lower end a sleeve 21 which surrounds and telescopes on the upper end of a compensating stationary tube 23 which is cylindrical and within it a rectangular tube 24 is see cured. The bottle support 15 has a bar 26 extending down from it through the sleeve 21 and rectangular tube 21 and lying against the inner wall of said tube 2 1 and having a longitudinal recess 27 therein. Said bar 26 has in its inner side a dog recess 22 in which a dog 28 is mounted. The recess is longer than the dog, asshown in Fig. 2, and the recess has a pocket 122 in its upper end into which the beveled end of the dog projects. The lower end of the dog is beveled with the inclination downward and toward the bar 26, as shown in Fig. 3. Said dog is held in place and controlled by a spring 29 which is in the chamber 27 and is connected by a link 30 with an arm 31 extending at a right angle from the dog 28. The upper end of the spring is mounted in a bracket 120 projecting from the bar 26 by means of a threaded rod 121 which has a nut 123 on its upper end. The nut 123 is accessible by merely unscrewing the sleeve 21 and without taking the device otherwise apart and in this manner the tension of the spring 29 is regulated for a purpose hereafter explained.

A fixed plate 33 is secured to the square tube 24 by bolts 341, see Fig. 5. An additional plate 35 is located between the inner Wall of the tube 2 1 and the fixed plate 33, and the latter is dove-tailed into the former plate, as shown in Fig. 3. The upper end of the fixed plate 33 is beveled downwardly toward the bar 26, that is, it has on its upper end an opposite bevel to'the bevel on the lower end of the dog 28. When the bottle support is in its upper position, as shown in Fig. 2, the spring 29 will act on the dog 28 to throw its lower free end over upon the beveled upper end of the fixed plate 33 in such a manner that the beveled plate 33 will resist a considerable downward pressure on the bottle support. WVhen, however, the downward pressure on the bottle support be comes sufliciently great, according to the adjustment of the spring 29, the lower end 'of the dog 28 will be forced laterally off the beveled upper end of the fixed plate 33, so that the dog will be forced into the recess 22 and the plate 33 will not thereafter resist the downward movement of the bottle support, and the lower limit of such downward movement is illustrated in Fig. 3. After the initial downward movement there is appreciably no resistance to farther downward movement so far as the dog 28 and beveled plate 33 are concerned.

Both the downward and upward movements of the bottle support are limited by a pin 40 which projects through the square tube 2 1 into a recess d1 in the bar 26, as shown in Figs. 2 and 3. In Fig. 2, said pin is limiting the upward movement of the bottle support, and in Fig. 3, it is limiting the downward movement thereof. The return or upward movement of the bottle support is caused by a relatively heavy spring 15 which surrounds the bar 26 and lies within the stationary tube 23 with its lower end resting upon the upper end of the square tube 24 which is stationary, and the upper end bearing against a collar 46 surrounding the bar 26 and held from upward movement by a pin 1 16 passing through the bar 26. The spring 15 is always tending to force the bar 26 and bottle support 15 upward and, therefore, said spring 45 has two functions. It resists to some degree all downward movement of the bottle support, thus cooperating in the initial downward movement thereof with the dog 28 and the plate 33. And the other function of the spring 45 is to return the bottle support from the position shown in Fig. 3 to its upper position. This action of the spring 45, however, does not affect the spring 29 which controls the dog, as the spring 29 connects parts associated with the bar 26 at fixed distances apart.

It will be obvious from the foregoing eX- planation how the machine accomplishes the objects mentioned in the introduction. It might be added that by having the arms 31 projecting from the dog 28 and the connecting bar 30 pivoted thereto and pivoted to the spring 29, it causes the straight pull of the spring and, therefore, reduces the tension of the spring and since the pull of the spring is to one side'of the fulcrum of the dog 28, it will tend to move the free end of the dog laterally into position on the upper end of the plate 33 and thus cause the dog to wedge in between the bar 26and the fixed plate provided with the inclined engaging surfaces which permit the dog to escape under excessive strain, and this protects the bottle on the upper end of the bottle support while being mounted. While the tubes 23 and 24B and plate 33 have been referred to as fixed or stationary, they are so called relatively to the bottle support. Means described in our former application and shown, but not described herein, at the proper time elevates and lowers the entire compensating structure. The bar 26 so far as the claims are concerned is considered a part of the bottle support as it may be integral therewith.

The invention is:

' 1.
